3 Diboron Compounds: Synthesis and Applications

Abstract

AbstractThis chapter describes the synthesis of symmetrical and unsymmetrical diboron compounds, and their synthetic applications for installing boron into organic molecules via activation of the boron–boron σ-bond under transition-metal/transition-metal-free catalysis. Because of the vast scale of these diboron-based boron-installing reactions, this chapter focuses mainly on the reactions with unsaturated carbon–carbon bonds such as alkynes and alkenes, α,β-unsaturated carbonyl componds, organic halides, and Caryl–H bonds. A discussion of the regio-, stereo-, and enantioselectivities of the boron-installing reactions is also included.
